My main problem is that a lot of the game messages aren't visible against the bright sand and sky. (This can be corrected by setting the 4th number in the game_text colours to 1-255. Higher than 0 = opaque text.) But otherwise, what a great job!

We should get that changeable sky map feature done so you can adjust the sky for each minigame and potentially multiple boards.

Oh yeah, on that one the platform doesn't always rotate either. Sorry, but I'm too lazy to figure out why that stuff happens.

You should be able to disable that game by removing "roller_try1" from the "roller_rand_option" entity (full-game mode), and replacing "bumper_start" with something else in the "next_game_rand2" entity (minigames-only mode).
